Asterophyllite is a mineral that is named after its star-shaped leaves. The spelling of Asterophyllite can be explained using the International Phonetic Alphabet (IPA). The first syllable is pronounced /æs/, rhyming with "gas". The second syllable begins with the "t" sound, followed by /ər/, pronounced like "fur". The third syllable is pronounced /oʊ/, like "oh". The fourth syllable features the "f" sound, followed by /l/, like "full". The final syllable contains the "ahyt" sound, like "height". Therefore, Asterophyllite is pronounced as æs-tər-oh-fil-ahyt.
The word "Asterophyllite" is derived from the Greek words "aster" meaning star and "phyllon" meaning leaf. Therefore, the word "Asterophyllite" literally translates to "star leaf". This name was given to the mineral due to its distinct star-like appearance and leaf-like structure.
